Description

[Detailed description of the invention] The present invention relates to a base material for laying floor finishing materials such as carpets, long flooring materials, tiles, etc. on a building frame. is formed of a non-woven fabric made of synthetic fiber such as polyester or glass fiber, and pressure-sensitive adhesives 2, 2' are applied in parallel lines of a predetermined width to both the front and back surfaces of the substrate 1 made of this non-woven fabric. The film is coated so that the lines intersect with each other, and release films 3 and 3' are adhered to the coated surface.

The pressure-sensitive adhesives 2 and 2' are made of adhesives that are well known in this field and can be repeatedly attached and detached, and are applied not over the entire surface and back surface of the substrate 1, but at predetermined intervals at appropriate intervals. Apply in parallel lines across the width. At this time, when the front surface is formed into a right-sloping linear shape, the back surface is coated with a left-slanted linear shape so that the linear shapes on both the front and back sides intersect with each other when viewed from the front or back surface. In this case, the inclination angle is in the range of 30 to 60 degrees with respect to the longitudinal direction of the substrate, preferably 45 degrees, so that the adhesives on both the front and back sides intersect. Furthermore, when applying the pressure-sensitive adhesives 2 and 2' in a linear manner to both the front and back surfaces of the substrate 1 made of non-woven fabric, the coating thickness, that is, the entire adhesive layer, is applied to both the front and back surfaces of the substrate 1. First, as shown in FIG. 2 when viewed minutely, the layers of adhesives 2 and 2' are applied in such a state that they have penetrated into the substrate 1 to some extent and the remaining layers protrude, and the layers of adhesives 2 and 2' that protrude are Release films 3, 3' are adhered to the surface of 2'.

The release films 3 and 3' are synthetic resin films such as polyethylene and polypropylene that have release properties, or synthetic resin films, paper, cloth, etc. that do not have release properties, and are treated with silicone treatment, Teflon treatment, or any other release treatment. A pressure-sensitive adhesive 2 is a thin film having so-called mold releasability, such as a processed one, and the releasable films 3, 3' are linearly applied to both the front and back sides of a substrate 1 made of non-woven fabric. , 2', and peeled off before use.

In this invention, pressure-sensitive adhesive is applied to both the front and back sides of a substrate made of non-woven fabric in a linear pattern that intersects with each other.
A releasable film is adhered to the coated surface, so it can be used as a floor finishing material for carpets, long flooring, tiles, etc.
When laying it on the building block B, peel off the release film on one side (it is arbitrary whether it is the front side or the back side) to expose the pressure sensitive adhesive layer, and then apply the exposed pressure sensitive adhesive to the building block B. After adhering to B, the releasable film on the other side can be peeled off and floor finishing material A can be laid. Since the adhesive is not coated on the adhesive, it can be adhered with good appearance without wrinkles, and it is also easy to peel off, making it easy to make corrections when reapplying or the like. In addition, since the pressure-sensitive adhesive on both the front and back surfaces is applied in a diagonal line shape and in a crisscross pattern with respect to the longitudinal direction of the substrate, it is easy to use when bonding base materials to concrete structures and floor finishing materials to base materials. Since the adhesive force is diffused along the application direction, the occurrence of wrinkles is constantly alleviated, and at the same time, air entrainment is also dissipated in this application direction, preventing the formation of bulges due to air entrainment. . It is even more effective when this angle of inclination is 30 to 60 degrees. Furthermore, even if the floor finishing material is hard and uncomfortable when walking, since there is a substrate made of non-woven fabric on the underside, the substrate becomes a cushion material and has elasticity like a foam sheet, which improves the feeling when walking. It will be good. Therefore, there is no need to manufacture a floor finishing material that incorporates a foam layer or the like, making it highly economical.
